N2 - A journal bearings-rotor system is under the influence of the interaction of nonlinear oil-film force, imbalance mass centrifugal force, journal whirling inertial force, rotor gravity and other external load (such as rub-impact force). A journal-oil film interaction balance equation is developed, which describes the correlation of journal whirling speed, rotating speed, oil supply pressure and bearing external load. Furthermore, a journal bearings-rotor system stability criterion and its application in the sense of engineering application are presented. According to a single-disk rotor supported on journal bearings experiment and micro turbine stability test, the mechanism of oil whirl and oil whip is illuminated and the practicability of journal bearing engineering stability criterion and its methodology is also validated.
